I suggest posting all you know about the John Reddington you are looking for such as who he married, children's names, where he lived, etc.The more you post the more we can help you.
If the John Reddington who was born Feb 27, 1875 is the person you seek his WWI draft card shows he was living in Haynes, ND. Nearest relative was Agnes Reddingon of the same address. The 1910 and 1920 censuses show John J. Redington and wife Agnes living in Kansas City, ND.
The 1900 census of Pittston, PA shows a John Reddington, born Feb 1875 as the son of the widowed Margaret, born May 1856. Sisters Margaret, born May 1877, and Elizabeth, born Feb 1884.
The 1880 census also of Pittston shows John 7, Margaret 3 and Martin 6 months as the children of Mich'l Redington 27 and Margaret 24.
